ASK FOR DETAIL

Introduction of RDP

Redispersible Polymer powder(ordinary type) is composed of a special polymer made of powder adhesive after spray drying. this powder is contact with water can be dispersed again in soon after forming an emulsion, and with the nature of the same as the initial emulsion, namely the film can be formed after the moisture evaporation, the film has high flexibility, high resistance to weathering and on various substrate with high caking property. the powder environmental protection, energy-saving, high quality, used for powder materials, dry-mix mortar is an indispensable functional additive. It can improve the performance of mortar, raise the strength of the mortar, improve the bonding strength of mortar with different base material, improve the mortar flexible and variable line, compressive strength, flexural strength, abrasion resistance and toughness, stick relay and water retention, constructability.

Properties

Re-dispersible emulsion powder is the powder form of a special emulsion (macromolecul-ar polymers) after spraying and drying. It dissolves in water easily and quickly and forms emulsion, the same with the original emulsion. The membrane will form after the moisture is evaporated; this kind of membrane possesses high flexibility, good climate resistance and high adhesive to various substrates.

Features

1. It has excellent resistance to saponification performance, especially suit for using with inorganic adhesives, such as cement, lime ,gypsum and plaster, or as a ingredient to mond.

2. Soft emulsion powder, dispersed in water to increase the adhesion between mortar and its substrates and improve the mechanic property and manageability of mortar. And it is no effect for mobility, thixotropy and water-holding capacity for the materials.

3. It has perfect compatibility to achieve the special performance mortar additives, and improve the mechanic property and construction of mortar.
